And it makes me glad to see someone hit a block as it gives me the idea that it can be done. Simultaneously it keeps me on my feet, since luck does not make a strategy.
I would advise you to research this issue and look at public statistics where they are available. Pay attention to the hashrates at which miners obtain their winning blocks. You'll be surprised to learn that the vast majority of blocks are obtained with higher hashrates, not with devices with only a few terahashes.
Ja.
If you check say, -ck's solo pool you will see that in the past few years yes, there have been a VERY few folks that got lucky running tiny hash rates (under 10TH).
However - the vast majority of winners there has been folks doing massive rentals ranging from a few hundred PH to almost 1 EH that ran for at least several days. Rentals of that size and time are
very expensive so those were some VERY expensive "Lottery tickets".
